Abstract

Le moule (70) destiné à fabriquer une partie coque d'une pale d'éolienne comprend une surface de moulage (76) ayant une forme qui délimite une surface de la partie coque. La surface de moulage a une direction longitudinale (114) et une longueur totale. La surface de moulage (76) comprend une partie flexible (72, 96) s'étendant dans la direction longitudinale de la surface de moulage (76) et ayant une longueur (l) correspondant à au moins 1/10 de la longueur totale (L) de la surface de moulage (76). L'invention se rapporte en outre à un procédé de fabrication de parties coques.
